RESUMO
Background: Chikungunya virus (CHIKV) is an infectious agent that caused several outbreaks among different countries and affected approximately 1.3 million Indian populations. It is transmitted by Aedes mosquito-either A. albopictus or A. aegypti. Generally, the clinical manifestations of CHIKV infection involve high-grade fever, joint pain, skin rashes, headache, and myalgia. The present study aims to investigate the relationship between the CHIKV virus load and clinical symptoms of the CHIKV infection so that better patient management can be done in the background of the CHIKV outbreak as there is no licensed anti-viral drug and approved vaccines available against CHIKV. Methods: CHIKV RTPCR positive samples (n = 18) (Acute febrile patients having D.O.F ≤ 7 days) were taken for the quantification of CHIKV viremia by Real-Time PCR. Clinical features of the febrile patients were recorded during the collection of blood samples. Results: The log mean virus load of 18 RT-PCR-positive samples was 1.3 × 106 copies/mL (1.21 × 103-2.33 × 108 copies/mL). Among the observed clinical features, the log mean virus load (CHIKV) of the patients without skin rash is higher than in the patients with skin rash (6.61 vs 5.5, P = 0.0435). Conclusion: The conclusion of the study was that the patients with skin rashes had lower viral load and those without skin rashes had higher viral load.
RESUMO
INTRODUCTION: Amphotericin B (AmB), a promising antifungal and antileishmanial drug, acts on the membrane of microorganisms. The clinical use of AmB is limited due to issues associated with its delivery including poor solubility and bioavailability, instability in acidic media, poor intestinal permeability, dose and aggregation state dependent toxicity, parenteral administration, and requirement of cold chain for transport and storage, etc. AREAS COVERED: Scientists have formulated and explored various covalent conjugates of AmB to reduce its toxicity with increase in solubility, oral bioavailability, and payload or loading of AmB by using various polymers, lipids, carbon-based nanocarriers, metallic nanoparticles, and vesicular carriers, etc. In this article, we have reviewed various conjugates of AmB with polymers and nanomaterials explored for its delivery to give a deep insight regarding further exploration in future. EXPERT OPINION: Covalent conjugates of AmB have been investigated by scientists, and preliminary in vitro and animal investigations have given successful results, which are required to be validated further with systematic investigation on safety and therapeutic efficacy in animals followed by clinical trials.

OBJECTIVES: To determine post-COVID syndromes in the Indian population, correlating a wide spectrum of post-COVID manifestations with acute disease severity and associated risk factors. BACKGROUND: Post-COVID Syndrome (PCS) is defined as signs and symptoms that develop during or after acute COVID-19 infection. DESIGN OF STUDY: This is a prospective observational cohort with repetitive measurements. METHODS: The study followed RT-PCR confirmed COVID-19-positive survivors discharged from HAHC Hospital, New Delhi, for a period of 12 weeks. The patients were interviewed over the phone at 4 weeks and 12 weeks from the onset of symptoms for evaluation of clinical symptoms and health-related quality of life parameters. RESULTS: A total of 200 patients completed the study. At the baseline, 50% of the patients were categorised as severe based on their acute infection assessment. At 12 weeks after symptom onset, fatigue (23.5%), hair loss (12.5%) and dyspnea (9%) were the main persistent symptoms. The incidence of hair loss (12.5%), memory loss (4.5%) and brain fog (5%) were found to be increased as compared to the acute infection period. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS, with high odds of experiencing persistent cough (OR = 13.1), memory loss (OR = 5.2) and fatigue (OR = 3.3). Further, 30% of subjects in the severe group experienced statistically significant fatigue at 12 weeks (p < .05). CONCLUSION: From the results of our study, it can be concluded that there is a huge disease burden of post-COVID Syndrome (PCS). The PCS comprised multisystem symptoms ranging from serious complaints of dyspnea, memory loss and brain fog to non-serious complaints of fatigue and hair loss. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS. Our findings strongly recommend vaccination against COVID-19, for protection from disease severity as well as prevention of PCS. RELEVANCE TO CLINICAL PRACTICE: The findings of our study support the multidisciplinary approach required for the management of PCS with a team comprising of physicians, nurses, physiotherapists and psychiatrists working in close coordination for the rehabilitation of these patients. As nurses are considered the most trusted professionals in the community and the class of health workers associated with rehabilitation, focus should be given to educating them on PCS, which would prove to be an important strategy for efficient monitoring and long-term management of COVID-19 survivors.

INTRODUCTION: Survival following lung transplant is low. With limited donor lung availability, predicting post-transplant survival is key. We investigated the predictive value of pre-transplant CT biomarkers on survival. METHODS: In this single-center retrospective cohort study of adults in a diverse, underserved, urban lung transplant program (11/8/2017-5/20/2022), chest CTs were analyzed using TeraRecon to assess musculature, fat, and bone. Erector spinae and pectoralis muscle area and attenuation were analyzed. Sarcopenia thresholds were 34.3 (women) and 38.5 (men) Hounsfield Units (HU). Visceral and subcutaneous fat area and HU, and vertebral body HU were measured. Demographics and pre-transplant metrics were recorded. Survival analyses included Kaplan-Meier and Cox proportional hazard. RESULTS: The study cohort comprised 131 patients, 50 women, mean age 60.82 (SD 10.15) years, and mean follow-up 1.78 (SD 1.23) years. Twenty-nine percent were White. Mortality was 32.1%. Kaplan-Meier curves did not follow the proportional hazard assumption for sex, so analysis was stratified. Pre-transplant EMR metrics did not predict survival. Women without sarcopenia at erector spinae or pectoralis had 100% survival (p = 0.007). Sarcopenia did not predict survival in men and muscle area did not predict survival in either sex. Men with higher visceral fat area and HU had decreased survival (p = 0.02). Higher vertebral body density predicted improved survival in men (p = 0.026) and women (p = 0.045). CONCLUSION: Pre-transplantation CT biomarkers had predictive value in lung transplant survival and varied by sex. The absence of sarcopenia in women, lower visceral fat attenuation and area in men, and higher vertebral body density in both sexes predicted survival in our diverse, urban population.

BACKGROUND: There is insufficient data on the prevalence and consequences of eating disorders in Type 2 diabetic patients. OBJECTIVE: To evaluate the presence of eating disorders (ED) and their association with glycaemic control and metabolic parameters in adult patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: A cross-sectional study on 145 patients was conducted in the medicine outpatient unit of HAHC Hospital, Jamia Hamdard tertiary care center. The Eating Attitudes Test (EAT-26) was used to screen for ED in adults with T2DM. The Score of less than 20 and more than 30 on EAT-26 questionnaire was defined as control for participants and relevant medical details like duration of treatment, glycaemic control, complications were recorded. RESULTS: A total of 145 diabetic individuals participated in this study. Out of these, 17.3% of individuals with T2DM screened positive for ED on EAT-26 scale and had a significant positive correlation in <20 groups and a significant negative correlation in >30 groups. CONCLUSION: Our study reveals that eating disorders are not very common in our clinical population of T2DM, the prevalence rates of eating disorders are lower in patients with T2DM than those reported from developed western countries.
RESUMO
Recently, breast cancer has reached the highest incident rate amongst all the reported cancers, and one of its variants, known as triple-negative breast cancer (TNBC), is deadlier compared to the other types of breast cancer due to a lack of feasible diagnostic techniques. Advancements in nanotechnology have paved the way to formulate several nanocarriers with the ability to deliver anticancer drugs effectively and selectively to cancer cells with minimum side effects to non-cancerous cells. Nanotheranostics is a novel approach that can be used in the diagnosis of disease along with therapeutic effects. Currently, various imaging agents, such as organic dyes, radioactive agents, upconversion nanoparticles, various contrasting agents, quantum dots, etc., are being explored for the imaging of internal organs or to examine drug distribution. Furthermore, ligand-targeted nanocarriers, which have the potential to target cancer sites, are being used as advanced agents for cancer theranostic applications, including the identification of various metastatic sites of the cancerous tumor. This review article discusses the need for theranostic application in breast cancer with various imaging techniques, the latest nanotheranostic carriers in breast cancer, and related safety and toxicity issues, as well as highlights the importance of nanotheranostics in breast cancer, which could be helpful in deciphering questions related to nanotheranostic systems.

INTRODUCTION: Healthcare workers (HCW) are most vulnerable to contracting COVID-19 infection. Understanding the extent of human-to-human transmission of the COVID-19 infection among HCWs is critical in managing this infection and for policy making. We did this study to estimate new infection by seroconversion among HCWs in recent contact with COVID-19 and predict the risk factors for infection. METHODS: A cohort study was conducted at a tertiary care COVID-19 hospital in New Delhi during the first and second waves of the COVID-19 pandemic. All HCWs working in the hospital during the study period who came in recent contact with the patients were our study population. The data was collected by a detailed face-to-face interview, serological assessment for anti- COVID-19 antibodies at baseline and end line, and daily symptoms. Potential risk factors for seroprevalence and seroconversion were analyzed by logistic regression keeping the significance at p<0.05. RESULTS: A total of 192 HCWs were recruited in this study, out of which 119 (62.0%) were seropositive. Almost all were wearing Personal protective equipment (PPE) and following Infection prevention and control (IPC) measures during their recent contact with a COVID-19 patient. Seroconversion was observed among 36.7% of HCWs, while 64.0% had a serial rise in the titer of antibodies during the follow-up period. Seropositivity was negatively associated with being a doctor (odds ratio [OR] 0.35, 95% Confidence Interval [CI] 0.18-0.71), having COVID-19 symptoms (OR 0.21, 95% CI 0.05-0.82), having comorbidities (OR 0.14, 95% CI 0.03-0.67), and received IPC training (OR 0.25, 95% CI 0.07-0.86), while positively associated with partial (OR 3.30, 95% CI 1.26-8.69), as well as complete vaccination for COVID-19 (OR 2.43, 95% CI 1.12-5.27). Seroconversion was positively associated with doctor as a profession (OR 13.04, 95% CI 3.39-50.25) and with partially (OR 4.35, 95% CI 1.07-17.65), as well as fully vaccinated for COVID-19 (OR 6.08, 95% CI 1.73-21.4). No significant association was observed between adherence to any IPC measures and PPE adopted by the HCW during the recent contact with COVID-19 patients and seroconversion. CONCLUSION: Almost all the HCW practiced IPC measures in these settings. High seropositivity and seroconversion are most likely due to concurrent vaccination against COVID-19 rather than recent exposure to COVID-19 patients. Further studies using anti-N antibodies serology may help us find the reason for the seropositivity and seroconversion among HCWs.

Background: This study examines quality of life (QOL) of a sample of police officers in India. The concept of QOL includes well-being, social obligations, relationships of a person, and his association with environment. The study examines the factors on which QOL of police officers depend and their relationships with each other. The issues linked with QOL are important because they directly affect the individual's ability to maintain a healthy lifestyle and affect organizational performance in the long run. This study explores relevant factors that have an impact on the QOL of the employees of police department in India. Method: In this paper, literatures review, ISM, MICMAC, and DEMATEL methodology have established eleven factors that impact the QOL of police officers in India. Mutual relations between factors have been established using the ISM approach to develop a model to represent these relationships. DEMATEL methodologies were used to analyze these factors. Results: Results indicate that "fair compensation, work overload, workplace safety, and job stress" are the top-level factors that affect QOL of police officers. Conclusion: The identification of factors and their mutual relationships that affect QOL are important for police officers and have to be dealt with according to their order of importance. The research model developed in this study shows how the factors of police officers' QOL are interrelated and presents the interrelationships among these factors. A comprehensive model depicting the relationships among these factors has been established, so that the QOL of police officers can be improved.
RESUMO
OBJECTIVE: This study investigated the use of routine contrast-enhanced chest computed tomography (CT) to diagnose unsuspected pulmonary embolism (PE). METHODS: All adult routine contrast-enhanced chest CTs performed at Montefiore in 2018 were included. Pulmonary artery enhancement was measured by placing regions of interest in the pulmonary vasculature. Adequate enhancement was defined as 200 Hounsfield units (HU) or greater. Presence or absence of PE was noted. Descriptive statistics and logistic regression analysis were performed. RESULTS: A total of 3164 CTs were evaluated (55.8% women; mean age, 63.2 years). Main pulmonary enhancement was highly correlated with peripheral enhancement. Of all cases, 28.7% (907 of 3164) reached the 200 HU threshold. Greater enhancement was associated with female sex, older age, outpatients, and contrast amount administered. Pulmonary embolism-positive cases comprised 1.8% (58 of 3164) of total cases. Furthermore, 39.7% (23 of 58) of PE-positive cases reached the 200 HU threshold. CONCLUSIONS: Over one quarter of routine contrast-enhanced chest CT scans met the 200 HU threshold indicative of adequate pulmonary artery enhancement, including nearly half of the 2% of examinations positive for PE.

Objective: Presently, evidence-based research studies on the efficacy of complimentary therapies like yoga for patients with different cardiac diseases are limited and conflicting. The objective of this study is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) on yogic interventions compared with usual care or non-pharmacological treatment in patients diagnosed with cardiac diseases. Methods: We conducted an electronic search of literature published from 2006 to May 2021 through five databases. PRISMA statement was used to develop and report a systematic review and meta-analysis protocol. Sixteen RCTs were included in the systematic review and 11 RCTs were used for meta-analysis. Outcome measures were blood pressure, lipid profile, and psychosocial measures. The Cochrane collaboration tool was used to assess bias risk. Results: The results show that yogic interventions resulted in significant reduction in systolic (d = 046; 95% CI.08-0.84; I2 = 81.86%) and diastolic blood pressures (d = 0.56; 95% CI.13-0.99, I2 = 84.84%). A medium statistically significant increase in HDL (d =0.67; 95% CI 0 to 1.33; I2 79.7%) and a low but significant effect on LDL (d = 0.23; 95% CI -0.08-0.54; I2 32.61%), total cholesterol (d =0.28; 95% CI -0.14-0.7; I2 63.72%), and triglycerides (d = 0.43; 95% CI -0.1-0.97; I2 76.64%) were observed. Pooled effect sizes showed a medium to low statistically significant effect on psychosocial indicators viz., QoL, stress, anxiety, and depression. Conclusion: The meta-analysis found strong evidence of effectiveness of yogic interventions on lipid profile, blood pressure, and psychosocial outcomes in patients with diagnosed cardiac diseases.
RESUMO
OBJECTIVES: India introduced BBV152/Covaxin and AZD1222/Covishield vaccines in January 2021. We estimated the effectiveness of these vaccines against severe COVID-19 among individuals aged ≥45 years. METHODS: We did a multi-centric, hospital-based, case-control study between May and July 2021. Cases were severe COVID-19 patients, and controls were COVID-19 negative individuals from 11 hospitals. Vaccine effectiveness (VE) was estimated for complete (2 doses ≥ 14 days) and partial (1 dose ≥ 21 days) vaccination; interval between two vaccine doses and vaccination against the Delta variant. We used the random effects logistic regression model to calculate the adjusted odds ratios (aOR) with a 95% confidence interval (CI) after adjusting for relevant known confounders. RESULTS: We enrolled 1143 cases and 2541 control patients. The VE of complete vaccination was 85% (95% CI: 79-89%) with AZD1222/Covishield and 71% (95% CI: 57-81%) with BBV152/Covaxin. The VE was highest for 6-8 weeks between two doses of AZD1222/Covishield (94%, 95% CI: 86-97%) and BBV152/Covaxin (93%, 95% CI: 34-99%). The VE estimates were similar against the Delta strain and sub-lineages. CONCLUSION: BBV152/Covaxin and AZD1222/Covishield were effective against severe COVID-19 among the Indian population during the period of dominance of the highly transmissible Delta variant in the second wave of the pandemic. An escalation of two-dose coverage with COVID-19 vaccines is critical to reduce severe COVID-19 and further mitigate the pandemic in the country.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) also referred as metabolic as metabolic (dysfunction) associated fatty liver disease. Type 2 diabetes mellitus (T2DM) is a major cause in progression of NAFLD and non-alcoholic steatohepatitis (NASH). The aim of the present study is to assess the activity of liver enzymes in T2DM in North Indian population. METHOD: This was a cross-sectional descriptive study clinic-based study in patients with T2DM. A total of 612 participants (226 healthy controls and 386 T2DM) were recruited. Body mass index (BMI), activity of liver enzymes including alanine and aspartate aminotransferase (ALT, AST) along with alkaline phosphatase (ALP) was measured. Fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c) along with total protein (TP) and albumin were also measured. Quantitative variables were expressed as mean ± SD, while qualitative variables as frequencies (%). Pearson/Spearman correlation test, unpaired t-test, Chi-squared test was used to assess the correlation, association and significant differences between study groups respectively. A P-value of < .05 was set as statistically significant. The Statistical Package for Social Sciences (SPSS) ® Statistics, version 23 (IBM SPSS Statistics, Armonk, NY) was used to for analysis of data. RESULTS: The study was conducted on 386 T2DM patients, and out of 386 patients, 139 (36.01%) were male (P < .000) and 247 (63.98%) were female. The mean age of the T2DM patients was 46.4 ± 13.6 years, while healthy individuals have mean age of 39.2 ± 12.0 years (P < .000). It was observed that the activity of AST in T2DM is comparable with the healthy persons (P = .060). While the level of ALT, total bilirubin and ALP in T2DM is significantly higher compared to healthy control (P < .000). On average, 62.53% of T2DM subjects and 32% of participants of healthy subjects had abnormal liver enzymes activity. CONCLUSION: The present study has revealed widely co-existent derangements in liver function tests (LFTs) in the diabetic population of North India. A detailed workup in such patients may be helpful in timely diagnosis and treatment. Moreover, early detection and management of abnormal liver parameters in T2DM would help minimize liver-related morbidity and mortality.
RESUMO
INTRODUCTION: Clinically measured Quadriceps angle (Q-angle) has low reliability. Measurement of angle between femoral shaft and patellar tendon (FSPT angle) on routine knee MRI was described in this study to represent the lateral vector forces of quadriceps mechanism. The cross-sectional study was designed to compare this angle between subjects with objective patellofemoral instability (PFI) versus those without PFI, to assess its reliability, and to assess its validity in terms of its ability to differentiate between PFI and non-PFI subjects using the "Receiver Operating Characteristic" (ROC) curve. MATERIALS AND METHODS: MRI scans of 20 subjects with PFI and 20 without PFI were obtained. FSPT angle was measured in each MRI by three different raters. In addition, the clinical Q-angle was also measured in the control group. RESULTS: The FSPT angle was significantly higher in PFI group as compared with the non-PFI group (p < 0.001). It had substantial inter-rater reliability of 0.82 (95% CI = 0.67-0.92) in the non-PFI group and 0.89 (95% CI = 0.78-0.95) in the PFI group. Test-retest reliability was more than 0.90. The AUC for the ROC curve was 0.86 (95% CI = 0.74-0.97). The clinical Q-angle measured in non-PFI subjects had inter-rater reliability of only 0.48 (95% CI = 0.21-0.72), and showed a fair correlation of 0.58 with the MRI angle. CONCLUSION: Measurement of FSPT angle was described on MRI with substantial intra-rater and inter-rater reliability. The angle was significantly higher in PFI versus non-PFI subjects and also showed a good ability to differentiate between these two groups in the ROC curve.

PURPOSE: Prevalence and sex differences of non-traumatic hemoperitoneum in the Emergency Department has not been studied in the literature. METHODS: Following IRB approval, multiple keyword searches were used to identify all cases of hemoperitoneum over a 55-month period. Cases were reviewed to confirm and quantify the hemoperitoneum. Maximum attenuation was used to grade blood density. Medical records were reviewed to determine cause, interventions and outcomes in each patient. RESULTS: Of the 171 verified cases of non-traumatic hemoperitoneum, 76% of cases were in women. CT exams in women were positive for hemoperitoneum 0.25% of the time, while 0.13% were positive in men. Regarding size, 25.7% were large, 24.5% were moderate and 49.7% were small. Contrast-enhanced studies had HU values of 103 ± 19 (range 47-146) which were significantly higher than for non-enhanced studies with values of 82 ± 19 (range 43-121, p < 0.001). The most common cause of non-traumatic hemoperitoneum was ruptured ovarian cyst which was found in 58% of women (76 cases). Of these, 69 patients received observation, 6 patients underwent surgery and 1 patient received Vitamin K. For the 95 non-ovarian cyst cases, 65% patients were admitted and then discharged, 22% were discharged from the ED, 12% expired and 1% were transferred to a different hospital. Post-procedure hemorrhage was the second to most common cause in women (24/130 = 18%) and the most common etiology in men (14/41 = 34%). CONCLUSIONS: In women, ovarian cyst rupture was the most common etiology of hemoperitoneum. Post-procedure hemorrhage was second in women and the most common etiology in men. Although unusual causes of hemoperitoneum will be encountered, understanding the most common causes of hemoperitoneum can provide a reasonable starting point when attempting to determine the most likely etiology of hemoperitoneum in any individual patient.

Chikungunya virus (CHIKV), an arthropod-borne Alphavirus is responsible for chikungunya disease. Arthralgia and arthritis are the major symptom. Some patients recover early while others for a very long time. This study provides, epidemiology and molecular characterization of three whole-genome sequences of CHIKV and assessed phylogenetic analysis, physiological properties, antigenicity, and B-cell epitope prediction by in silico. We report the clinical epidemiology of 325 suspected patients. Of these, 118 (36.30%) were confirmed CHIKV positive by either PCR or ELISA. Clinical analysis showed joint pain, joint swelling and headache were frequent and significant features. Phylogenie analysis showed the currently circulating strain is in close clustring to Africa, Uganda, and Singapore CHIKV strains. Molecular characterization by WGS was done. Thirty eight amino acid changes in the nonstructural proteins were found with respect to the S27 (ECSA) strain. Of these five located in nsP2. Similarly, 34 amino acid changes in structural proteins were observed. The major change was notice; in E3 protein hydropathicity -0.281 to -0.362, in E2 isoelectric point (pI) 8.24 to 8.37, instability index 66.08 to 71.062, aliphatic index varied from 74.69 to 68.59 and E3 75.79 to 70.05. In nsP1 protein pI varies from 6.62 to 8.04, while no other change was observed in structural and nonstructural protein. The linear B-cell epitopes, position, and number varied with the mutation. The molecular characterizations of WGS demonstrate the observation of protein, antigenicity with respect to the mutation.

BACKGROUND AND AIMS: Type 2 Diabetes Mellitus (T2DM) is known to be associated with an increase in total plasma free fatty acid (FFA) concentration. The present study was conducted to determine the changes in plasma fatty acids at different levels of glycation in type 2 diabetes mellitus. METHODS: The study involved 50 subjects having different levels of glycation (HbA1c 4.9-15.0%) and further categorized in 5 groups [group 1 (HbA1c <6%), group 2 (HbA1c 6-7%), group 3 (HbA1c 7.1-9%), group 4 (HbA1c (9.1-12%) and group 5 (HbA1c >12%)] with 10 subjects in each group. RESULTS: A total of 19 free fatty acids were detected by gas chromatography-mass spectrometry (GC-MS) analysis in the plasma samples. The levels of lauric acid (C12:0) and stearic acid (C18:0) were significantly raised at an advanced stage of glycation (HbA1c 9.1-15%). Long-chain fatty acids, pentadecanoic acid (C15:0) and palmitic acid (C16:0) levels were elevated in hyperglycemia as compared to normoglycaemic subjects (HbA1c <6%). Moreover, levels of mono and polyunsaturated fatty acids, oleic acid (C18:1) and linoleic acid (C18:2, w6) were significantly decreased in patients with increased levels of glycation (HbA1c 6-15%). CONCLUSION: GC-MS is a novel way to study the plasma fatty acid profiling and findings of this study suggest that monitoring alterations in plasma FFA profile may be of prognostic value.

Chikungunya virus (CHIKV) infection causes acute febrile illness in humans, and some of these individuals develop a debilitating chronic arthritis that can persist for months to years for reasons that remain poorly understood. In this study from India, we characterized antibody response patterns in febrile chikungunya patients and further assessed the association of these initial febrile-phase antibody response patterns with protection versus progression to developing chronic arthritis. We found 5 distinct patterns of the antibody responses in the febrile phase: no CHIKV binding or neutralizing (NT) antibodies but PCR positive, IgM alone with no NT activity, IgM alone with NT activity, IgM and IgG without NT activity, and IgM and IgG with NT activity. A 20-month follow-up showed that appearance of NT activity regardless of antibody isotype or appearance of IgG regardless of NT activity during the initial febrile phase was associated with a robust protection against developing chronic arthritis in the future. These findings, while providing potentially novel insights on correlates of protective immunity against chikungunya-induced chronic arthritis, suggest that qualitative differences in the antibody response patterns that have evolved during the febrile phase can serve as biomarkers that allow prediction of protection or progression to chronic arthritis in the future.

Diabetes mellitus is associated with increased levels of inflammation and oxidative stress in patients. The aim of the present study was to test the hypothesis that aqueous extract of Cichorium intybus seeds (AECIS) would have add-on beneficial effect in type 2 diabetes mellitus (T2DM). In this double-blind randomized clinical study, 150 subjects were enrolled to assess the add-on efficacy and safety of AECIS in T2DM patients. The subjects were randomized (1:1) to the AECIS (n = 51) and placebo (n = 49) groups. The subjects in both groups continued to take prescribed doses of metformin. The standardization of AECIS was carried out by liquid chromatography-mass spectrometry and phytochemical analysis. The mean hemoglobin A1c (HbA1c) level in the AECIS and placebo groups at baseline was 8.6% and 8.5%, respectively. Mean values of HbA1c at the end of 12 weeks of intervention were 7.42% in the AECIS group (a reduction of 1.18% from baseline) and 8.4% in the placebo group (mean reduction of 0.1% from baseline). Besides, significant reduction in inflammation, oxidative stress, and hypertriglyceridemia was seen in the AECIS group (p < .05). The study shows for the first time that AECIS supplementation ameliorates the disease progression and it is beneficial as a potential adjunct dietary supplement for the management of T2DM.

Triple-negative breast cancer (TNBC) is a highly malignant subtype of breast cancer associated with poor prognosis. Although conventional chemotherapy regimens have shown some effectiveness in early TNBC cases, the outcome in advanced stages is poor. The PI3K/AKT/mTOR pathway is one of the important and active pathways involved in chemoresistance and survival of TNBC. This pathway is speculated to play an important part in malignant transformation and has been considered as a potential molecular target for the design of therapeutic agents to treat TNBC. This review discusses the potentials and drug discovery perspectives of PI3K/AKT/mTOR as a therapeutic target for effective management of TNBC with anticipated challenges.
